Sensor component, sensor control and current measurement circuit

Abstract: The sensor assembly (14) comprises a sensor device (51) for non-contact detection of intensity of the electrical current (Im) and sensor device (53) for detection intensity of electrical current. The sensor devices have a common measurement range. An analog-digital converter (41) converts analog measured values (U1) from sensor device into digitized measured values (U1D). The sensor devices and analog-digital converter are arranged on a common circuit carrier. Independent claims are included for the following: (1) sensor controller for controlling sensor assembly; and (2) current sensing circuit for measuring strength of electric current.

Displacement inductive sensor: Simulation tool algorithm

Abstract: This paper presents a planar displacement inductive sensor for the detection of small displacements (less than 0.5 mm) in a plane, usable in robotics. It also describes design, realization and the input inductance measurement of the sensor. Displacement in two directions could be detected using two sensor elements. Each element consists of a pair of meander coils. The variation of input inductance between coils serves as a measure of displacement. In order to achieve a wider measurement range of the sensor, gaps were inserted in a coil of sensor element. An additional extending of the measurement range was achieved by analyzing structures with less turns of meander coils, as well increasing width of conductive segments of the coil with inserted gaps. A new simulation tool in MATLAB for evaluation of the input impedance of the sensor was developed. A brief explanation of simulation tool algorithm was presented.

Pliable heating device

Abstract: The invention relates to a pliable heating device having a flexible electrical heating apparatus (10) which is operated by means of a control apparatus and which has at least one flexible heating element (16) which is connected to a flexible support (15) and which has a heating conductor (Rhi), which is part of a heating circuit (100), and a flexible sensor conductor (Rho) which is separated from said heating conductor by means of an intermediate insulation means (ZW), having an oscillator (60) which is contained in the control apparatus, is connected to the sensor conductor (Rho) and can be attenuated and of which the output signal can be varied as a function of various functional states of the heating apparatus (10) which are detected by means of the sensor conductor (Rho), and having an evaluation device (301) by means of which fault states can be detected from the output signal In order to reliably identify functional states, in particular fault states, provision is made for the sensor conductor (Rho) firstly to be connected to the heating conductor (Rhi) by means of an impedance arrangement which is connected in series with said sensor conductor and comprises at least a resistive sensor impedance (RS), a capacitive sensor impedance (CS) and/or an inductive sensor impedance (LS), and secondly is connected to the oscillator (60) by means of a resistive current-limiting impedance (R17)

Segmented core for an inductive proximity sensor

Abstract: An inductive proximity sensor for sensing the presence of target based on a change of inductance in the sensor. The sensor includes a coil and a core formed of a permeable material so as to form an electromagnetic field when the coil is electrically driven. The core has a base, a central post, an outer wall, and at least one slot. The central post extends distally from the base and through the coil and defines a distal end. The outer wall extends distally from the base and around the coil and also defines a distal end. The slot or slots are for enhancing the performance of the sensor by reducing eddy current losses in the core. Each slot extends at least partially along a path defined from the distal end of the outer wall to the base and from the base to the distal end of the central post.
